Applying Rotational Velocities

You can apply a rotational velocity to prescribe an angular velocity about a specified axis.

Before you begin: The model must have at least one rotational degree of freedom.

Support Selection
  1. From the Loads section of the action bar, click Applied Rotational Velocity .
  2. Optional: Enter a descriptive Name.
  3. Select the geometry supports in the model.

    A rotational velocity can be applied to one or more points, edges, or faces. You can also select a coupling connection, rigid body, or rigid surface; the velocity is applied to the reference point for the feature.

    You can apply the rotational velocity to a secondary base by selecting Sim feature as the type of support, then selecting the appropriate displacement restraint from the window that appears.

  4. Enter the Rotational velocity magnitude.
  5. Select a DOF representing the axis of rotation for the velocity within the selected axis system.
  6. Select one of the following as the Axis system definition:
    OptionDescription
    Global Aligns the local feature triad with the global coordinate system.
    Implicit Aligns the axis system to the transformed axis system applied on the support.
    Local Aligns the local feature triad with a selected axis system in the model. If you select this axis system, you must also specify whether the axis system is Cartesian or Cylindrical.
    Specify Orients the local feature triad directly. Right-click the feature triad glyph on the model, and select an orientation tool.
  7. Optional: Enter a Scale factor that is applied to the magnitude in each step.
  8. Select an Amplitude that defines the magnitude during the step.
  9. Click OK.
